Hello,
I am trying to test the node-protection feature in a lab using an MX5
router with logical-systems and I can't find the reason why is not
working.The topology I use is here:

All routers are configured for mls,rsvp,ospf,link-protection, but when I
disable the interface between P1 and PE1, the LSP between PE1 and PE2 goes
down and stay that way:
Before disabling the interface:

"198 Aug 10 12:04:44.607 172.22.205.1: Non-RSVP capable router detected"
seems to be very clear,but it is not, because all routers are rsvp enabled
